FOUNTAIN-PEN.

1,107 ,641, Specification of Letters Patent.

Application filed January 24, 1912.

Patented Aug. 18, 19141.

Serial No. 673,187.

To all whom it may concern:

Be it known that I, ANGELO BADINI, a citizen of the United States, and a resident of New York, county and State of New York, have invented a certain new and use ful Improvement in Fountain-Pens, of which the following is a full, clear, and exact specification.

A further object of the invention is to provide a new and novel element or tip having a plurality of inclined converging grooves or channels serving to permit the inks to be fed with regularity to the pen points and which will allow sufficient air to be admitted to each of the chambers of the reservoir to replace the ink as it is consumed therefrom, and a further object is to prevent the stoppage of the flow of ink from the pen by reason of lodgment of sediment or other substance, in the groove of the feed.

A practical embodiment of the invention is represented in the accompanying drawing forming a part of this specification in which similar characters of reference indicate corresponding parts in all the views, the said invention being more fully described hereinafter and then pointed out in the appended claim.

In the drawing, Figure 1 is a longitudinal section, partly in detail, of one form of fountain pen embodying my invention. Fig. 2 is a side view of the feed element. Fig. 3 is a section taken on the line II--II of Fig. 2, and Fig. 4 is a top plan of the feed element. 1

The fountain pen 10 has an elongated tubular reservoir or handle 11 which may be of any desired length and size, and said reservoir is divided into two chambers 12 and 13 which is provided by a partition 14: formed interiorly thereof. Each end of the tubular reservoir or handle 11 is tapered, at 15 and 16, whereby a cap, as shown in dotted lines at 15* and 16, may be removably held thereon as is incident to fountain pens in ordinary use.

The free ends of the tapered portion of the reservoir 11 are interiorly threaded for reception of the threaded end of tapered sleeves or tubular members, as 17 and 18, whereby the sleeves may be removed when it is desired to place a suitable quantity of ink within the chambers 12 and 13. In the passage through each of the sleeves 17 and 18 is removably held a feed element or tip 19 and 20.

Fach of the feed elements or tips 19 and 20 has a circular body 21. One end of the circular body 21 is cut away or beveled, as at 22, and the upper portion of the opposite ends of said tips are also cut away or here-led, at 23, whereby recesses, as 24 and 25, Fig. 1, are provided when the parts of the pen a re assembled. Upon the top surface of the beveled ends 22 of each of the tips 19 and 20 is a pen point 26 and 27 which is held against displacement by being guided, as illustrated, between each of said tips and the interior surface of the sleeve thereon.

In order to permit the ink from the chambers 12 and 13 to be fed with regularity to the pen points 26 and 27 respectively, in the top surface of the body of each of the feed elements or tips 19 and 20 are provided grooves 28 and 29. The grooves 28 and 2b are spaced apart for a considerable distance, and converge into each other adjacent to the top of the beveled end 22 of the tips as well as being graduated in depth or disposed on an incline, as shown by the dotted lines at 30. Fig. 2, whereby an ample supply of the ink will be received by said grooves from the chambers of the reservoir. In this manner a ridge 31 is provided between the grooves 28 and 29 and said ridge is of a height whereby a space 32. Fig. 3, is provided, between the top surface of each ridge and the inner surface of the sleeve thereon so as to admit air into the chambers 12 and 13 of the reservoir as the ink is consumed therefrom when the fountain pen is in use.

By providing two converging grooves in. the top surface of the feed bar and arranging the grooves to extend the length of the bar the possibility of stoppage of the flow of ink is decreased for the reason that if there is but one channel for the ink to flow in and if that is stopped the supply of ink will be out 01f, but with two channels if one is stopped the ink may flow through the other.

In operating my fountain pen, and when it is desired to use two different colors of ink at separate intervals, black ink may be placed in one of the chambers 12 and 13 of the reservoir and red ink may be placed in the other chamber after the tapered sleeves 17 and 18 are removed from the reservoir. When the sleeves 17 and 18v are re-applied upon the reservoir the fountain. pen may then be employed for writing in. the usual manner, in either of the colored. inks, thereby permitting the use or two distinct pens to be dispensed with as well as allowing the writer to have for convenient use inks of different colors.

In the foregoing description I have embodied the preferred form of my invention, but I do not wish to be understood as limiting myself thereto, as I am aware that modifications may be made therein Without departing from the principle or sacrificing any of the advantages 0t this invention, therefore I reserve to myself the nght to make such changes as fairly fall within the sco e thereof. Q

aving thus descr bed my lnventlon, I

mower This specification signed and witnessed this twenty-third day of January, A. D, 1912. I ANGELO BADINI.
